The mechanism for controlling said abutments and exhaust ports is operated by means of the handle 74 and consists of t..vo pairs of rods 75 ,extending in opposite direcH tions from said lever and connected at their ends to thev valves for controlling'the exu haust ports so that'when said lever is moved in opposite 'directions said ports Will bel alternately opened and,closed.- The `rods ofv 'each pai-rk Aextend on o posite sides ofY theV body and eachl of saidP p lmediate its endsan'angular pin TGadapted rods carries interf to extend through a rsuitable peningfornied in the adjacent lateral extension -67 so that when the abutments v65a`re moved to open ,position in passingtherebetween, saidpins may be caused, by an op'e'iati'n of; the' lever 74, to engage in recesses 77v formed inv saidabutments and thereby retain" the abutments in their open position. Thus when it is deJ sired to ,maintain the abutments'' at the lett of Figure 5' in open position, the leve-r 74 Abe 'shifted vtothe left in order 'to project the pins 76 at theleftf-into'the ex# tension 67 so that the Ssamevvillengage in the recesses 77 upon Y' they next'fopening'of said abutments.
